Midibud

MidiBud is a DIY MIDI controller with a 16×2 display, EEPROM, push-button encoder and 5 buttons. The design is based on the Mutable Instruments MIDIpal. This is a revision of the board made by the Midisizer guys, so you can order your own PCB + Atmega Pre-programmed, get the list of components and build your own!!

What is MIDIPAL?:

Composition tools:

• Keyboard-controlled drums sequencer. Control a drum module from a keyboard by triggering and combining patterns — one for each key of a 49 keys keyboard. Create mesmerizing Euclidean drum patterns.
• Note randomizer: Randomize note values, velocity, and send random CC at each key press.
• Chord memory: Enjoy the classic chord memory feature of early 80s synths.
• Arpeggiator: Arpeggiate your chords. 4 modes (up, down, up&down, random), 15 rhythmic patterns, adjustable tempo, rhythmical division, gate and groove, syncable to MIDI clock.
• Delay: ay ay ay… Up to 32 echoes added after each note, transposition and velocity adjustment for creating feedback arpeggio effects, syncable to MIDI clock.
• Scale: Never miss a note in a solo… The scale mapper replaces each note you play by its nearest neighbour in one of the 25 preset scales.
• Step sequencer: The tiniest step sequencer! Up to 32 step can be sequenced, with note duration, note value, velocity, and CC control at each step.

MIDI Message generation:

• Clock: Make your MIDI setup groove! MIDI clock source with adjustable tempo and adjustable groove/shuffle/humanization patterns, from super-tight to funky.
• CC LFO: Generate up to 4 tempo-synced LFO and cyclic automation movements for any MIDI Control Change (CC) message.
• CC knob: Use the MIDIpal as a knob to send any CC or NRPN message.
• Controller: Up to 8 sensors / potentiometers (or any voltage source) can be connected to the MIDIpal board, turning it into a versatile “brain” for sensing applications.
• Ear training game: A fun note / interval recognition game.

MIDI Plumbing:

• Monitor: Sometimes things go wrong with a MIDI setup… Use the MIDIpal as a trusted source to display the stream of MIDI messages coming from a cable.
• BPM counter: Use the MIDIpal to check the accuracy of a MIDI clock signal coming from a sequencer or drum machine.
• Channel filter: Remove all MIDI messages coming from a specific channel.
• Splitter: Control several synths from a single keyboard by routing one half of the keyboard to a MIDI channel, the other half to another.
• Dispatcher: Play a rack of monophonic synths like a polysynth. The MIDIpal will automatically route each note of a chord to a differentMIDI channel.
• Channel Merger: Merge several MIDI channels into a single MIDI stream.
• Clock divider: Create a slower subdivision of a MIDI clock.

CNC enclosure build:

For this occasion I have decided to use what I have learned in the last projects, combining the idea of ​​ETHERUS and the first CerebelUSB case. The main panels are made of acrylic, spray painted, then CNC drilled and engraved, then painted black again for a nice contrasting text.

The side panels are not just for freaking out… They are actually what keep the entire case in one piece, like a puzzle, I love this way of designing cases.

I’ve had to wire the MIDI connectors off the board so I can fit them in accordingly, they should go on the top but this makes it impossible to close it off with a case. The same is also true of the power connector, which has been reversed to the bottom of the PCB.

Files:

Due to the number of people asking me for these files for CNC, despite my comments about the difficulty. Here I leave DXF files for the wooden front, back and sides. Enjoy!
